?Recommended for DIY enthusiasts!

?Solves the hassle and difficulty of collecting various spiral bits.

?No need to switch bits with a step drill (tapered drill).

?Eliminates the tedious process of changing bits.

? How to Use

?First, mark the material you want to drill, such as wood, stainless steel, plastic (like PVC pipes), or sheet metal (like iron pipes).

?Since a step drill cuts as it drills, you can prevent mistakes by slowly drilling while checking the hole size. However, to avoid drilling the hole too large, mark the desired depth with masking tape on the surface.

?Once marked, attach the step drill to your drill driver.

?Make sure it is securely centered when attaching.

?You can check if it's centered by running the drill briefly without load.

?Once correctly attached, drill the hole in the material.

?If you are using a step drill that is larger than the desired hole size, drill while visually checking to avoid accidentally drilling to the maximum size of the bit.
